Visual Studio build successful, MSBuild fails

Question

I am trying to clean and rebuild a solution file with multiple projects from the command line using MSBUILD. For some reason my build fails (about 10% of the built projects fail

Answer 1

I assume there's a difference in how the project is built, because Visual Studio does not run MSBuild, as it rather hosts the build engine itself. This was answered here.

However, I've had similar problem.

In my case the project referenced an external library, which was placed in the project's child directory, unluckily named "packages".

After running MSBuild the folder's content was deleted, supposedly to be downloaded again by Nuget.

The obvious solution was to rename the folder and it worked.
